Endoscopic ultrasound-guided biliary drainage vs percutaneous transhepatic biliary drainage for malignant biliary obstruction after endoscopic retrograde cholangiopancreatography failure

Abstract

In a recent issue of the World Journal of Gastrointestinal Surgery, a meta-analysis investigated the safety and efficacy of electrocautery-enhanced lumen-apposing metal stent (ECE-LAMS) implantation for managing malignant biliary obstruction following failed endoscopic retrograde cholangiopancreatography. This manuscript endeavors to offer a comprehensive look at the progression of endoscopic ultrasound-guided biliary drainage (EUS-BD) technologies, weighing their merits and drawbacks against traditional percutaneous methods. Several meta-analyses and randomized controlled trials have compared the performance of EUS-BD and percutaneous transhepatic cholangiodrainage (PTCD). These studies revealed that the technical success rate, clinical success rate, and adverse events were similar between EUS-BD and PTCD. Nevertheless, given that most of these studies predate 2015, the safety and effectiveness of novel EUS-BD techniques, including ECE-LAMS, compared with those of percutaneous biliary drainage remain elusive. Further investigation is imperative to ascertain whether these novel EUS-BD techniques can safely and efficaciously replace conventional percutaneous therapeutic approaches.
